A social network is an online community of people who share personal or professional interests or activities, or who are interested in sharing the interests and activities of others. It provides a variety of ways for users to interact and share information such as email and instant messaging. It can provide a means to connect with friends or classmates and a recommendation system linked to trust.
it can also be described as:
Any website designed to allow multiple users to publish content themselves. The information may be on any subject and may be for consumption by (potential) friends, mates, employers, employees, etc. The sites typically allow users to create a "profile" describing themselves and to exchange public or private messages and list other users or groups they are connected to in some way. There may be editorial content or the site may be entirely user-driven. Content may include text, images (e.g. (http://flickr.com/)), video (e.g. (http://youtube.com/)) or any other media.
YouTube is a video sharing website on which users can upload and share videos. Unregistered users can watch the videos, while registered users are permitted to upload an unlimited number of videos. Videos that are considered to contain potentially offensive content are available only to registered users over the age of 18.
Teacher Tube
TeacherTube is a video sharing website similar to, and based on, YouTube. It is designed to allow those in the educational industry, particularly teachers, to share educational resources. The site contains a mixture of classroom teaching resources and others designed to aid teacher training. A number of students have also uploaded videos that they have made as part of K-12 and college courses.
Twitter
is a free social networking and micro-blogging service that enables its users to send and read messages known as tweets. Tweets are text-based posts of up to 140 characters displayed on the author's profile page and delivered to the author's subscribers who are known as followers. Senders can restrict delivery to those in their circle of friends or, by default, allow open access. Users can send and receive tweets via the Twitter website, Short Message Service (SMS) or external applications. While the service costs nothing to use, accessing it through SMS may incur phone service provider fees.
Blog
Short for Weblog, a Blog is a type of website, usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order.
Many blogs provide commentary or news on a particular subject, some function as more personal online diaries, others are used to compile information on a particular topic.
A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blogs.
The collective community of all blogs is known as the blogosphere. It is the concept that blogs exist together as a connected community (or as a collection of connected communities) or as a social network where everyday authors can publish their opinions.
A wiki is a Web site that allows users to add and update content on the site using their own Web browser. This is made possible by Wiki software that runs on the Web server. Wikis end up being created mainly by a collaborative effort of the site visitors.
A great example of a large wiki is the Wikipedia, a free encyclopedia in many languages that anyone can edit. The term "wiki" comes from the Hawaiian phrase, "wiki wiki," which means "super fast." The presumption being, that if you have thousands of users adding content to a Web site on a regular basis, the site could grow "super fast."

Different sites have different emphasis. For example, (http://friendsreunited.co.uk) (one of the earliest such sites) focuses on listing former acquaintances; (http://myspace.com) is music-oriented; (http://linkedin.com ) aims to connect business partners; (http://del.icio.us), (http://stumbleupon.com/) and (http://digg.com) are for exchanging links to favorite web sites. There are many more.
Modeled after a book which showed the faces and names of students and faculty, Facebook (http://facebook.com) is the most used social networking site.
